Microsoft 365 Security Assessment
Microsoft 365 is a mission‑critical platform for email, collaboration, identity, and data storage and one of the most targeted environments by threat actors. While Microsoft includes powerful security capabilities, many are not enabled or securely configured by default, leaving organizations exposed to account takeover, data leakage, and compliance risk.
An SBS CyberSecurity Microsoft 365 Security Assessment provides a comprehensive, expert‑led review of your Microsoft 365 tenant to identify misconfigurations, reduce attack surface, and align your environment with industry‑recognized security best practices.

What Is a Microsoft 365 Security Assessment?
A Microsoft 365 Security Assessment is a focused security configuration review of your Microsoft 365 tenant. SBS CyberSecurity evaluates your environment against industry best practices, including the CIS Microsoft 365 Foundations Benchmark and Microsoft security guidance, to identify high‑risk settings and improvement opportunities.
This is not an automated checklist or penetration test. Our approach combines technical validation with business context to ensure recommendations are practical, prioritized, and defensible.
